The primary object ofV this invention is the provision, inca manner as hereinafter,

set forth, of a connectingor coupling device adapted to be attached toa sulky plow in such a manner that a walking plow may be attached to the sullr'y to arrange the walkingplow in the same relation with respect to the series of plows carried by the other. Y y Y Still another object of this invention is the provisiomin a manner'as hereinafter set forth, of a coupling device for the purpose above set forth which will be vstrong and sturdy, Vand will act to maintain the attached or walking plowV in the proper position with respect toV the plows carried by the sulky, under all conditions.

A` further and final object of the invention is the provision, in a manner as hereinafter set forth, of an attaching bracket of the class described which is lof simple construction, easily and quicklyattachable or detachable, and positive and satisfactory in action.

The invention will be best understood by means of the device embodying this invention.

Figure y2 is a top plan view of the rear por? tion of the sulky plow' and of. the walking plow, showing the device embodying this inA Vand in top plan view.

sulky as each of the series bears to one anvThe Figure 1 shows in side elevation a sulky s plow and a walking plow attached thereto vention connecting lthe rtwo plows together Figure 3 is alongitudinal sectionalview through the connecting brackets embodying this invention. f f f yFigure 4L is a Section taken upon the line i-tof .Figure 3 and,

Figure 5 is a rear vView of the bracket embodying this invention;

Referring now tothe drawing in detail kwherein like numerals of reference indicate` corresponding parts throughout the several views, there is indicated by thek numeral 1 the frame of .a sulky plow.` Carried vupon the plates 2 which are secured tothe sides of the framel, is a transversely extending shaft3 to which shaft 3 arms4 are lsecuredascshown in Figure 2. These arms normally extend downwardly from .the shafty 3 and have pivotally secured y -to their lower ends the plow rbeams 5. These plow beams 5 extend forwardly to a common head 6 Vto which a lclevis 7 is pivotally at-r i tached for connection with` a tractor or power means., The'rea-r endsof the beams 5 are curved downwardly as indicated at 8 and carry at their lower ends the plows 9. As is clearly shown the plows 9 are in stag-` geredrelation. n Y,

bracket 2 has pivotallv attached thereto.l a footvlever 10, which is attached to the shaft 3 and byfwhichthe operator of the machine can revolve the shaft to lift the plows 9. c v

The usual axle 11 is carriedk bv the frame 1 upon which the side wheel 12 is mounted.

The rear portionl of the frame 1 `is eX- Vtended as at 13 andcarries 'thereon a bearprises a bracket structure indicated generally bythe numerall. This bracket is of aV flat steel bar bent intermediate its ends at the points 18 to set up they verticaly u per portion 19, the obtusel angled interme iate.

portion 20 and the horizontal terminal lower' portion. 21. Secured by means of the rivets beam 5 therebetween.

22 to the back of the bar 17 and extending throughout the length thereot1 is a steel strap 23 which is also bent to set up upper, intermediate and lower portions 24, 25 and 26 respectively. The intermediate portion 25 of the strap 23 is of greater length than the intermediate portion 2O of the bar 17 and extends in such a manner as to space the upper portion 2e from the upper portion 19 as is shown. The lower'portion l26`of the strap 23 is also of greater length thanY the lower portion 21 of the bar 17`and eX- tends beyond the terminal end thereof, and

secure-d to the upper side of the lower port-ion 21 ofthe bar`17 is a second short strapf27 which is also of greater length than the portion 21 extending beyond Vthe end of the same and overlying and spacedv from the ext-ended end of the portion 261 setting up.

tures 34 formed `through theA portions 19 and' 24; of the bar 17and strap 23, are loosened and removed, and the device is so placed upon one of the beams as to position the portions one on either side of the beam whereupon the bolts 33 are replaced one above and the otherbeneath the beam and the nuts thereof threaded thereon to draw the members `19 and 24 togetherto bind the As shown the beam selected is that one which extends farthest to the rear of 'the implement which is alsol the one near the'inside of the implement and whenthe bracket is thus attached Ato the bea-m a portion thereofr or horizontalsection, will extend laterally from,y the implement.` The device will then assume the position shown in Figures 1 and2 and the yoke 30 will bev directed toward the rear of the im plement and the yoke 32 willbe directed toward'the front thereof.

lVhen the device is thus secured in position upon-the plow beam 5, achain 33 is secured at one end to the forwardly directed yoke and the other endof the chain is carriedto the head 6 of the implement whereit is att-ached as at 34 thereto. The clevis l36 ofv a walking plow'indicated 'gene erally by the numeral 37'is then' 'positioned' between the-ends of the arms of the yoke ing between the attachment and the head of,the..sulky plow thev attachment isprevented from beingtwisted towardgthe rear ofy the implement.

From the foregoing description it will be readily seen that there'has been -provided a `very-unique and novel means forattaclr ing',a walk}ing plow to a sulkyplow ina desirable manner, which means is 'strongyand durable, inexpensive to manufacture and easily and quickly attached.

l-lavingthus describedmy invention what Ilclaim is 1. Av device for coupling a walking plow to a sulky.,V plow, comprisingra'bar member having averti'cal and a'horizontal portion, means for securing said .vertical portionfto a beam of said sulky plow, and pivoted means carried at the free end'of'said horizontalportion for setting up' a pivotal connection with thegbeanrofa walking plow.

2. A'device for couplin'gera walkingplow to asulky plow, comprising a bar member havingy a'vertical and a yhorizontal portion, means for securing said vertical portion to abeam of said sulky plow, means carried at the free end of-'said horizontal'portion for setting, up. a pivotal connection with the beam ofa walking plow, and means connecting the free end of'Y said horizontal portion with'the forward part of the sulky plow for assisting to maintain said member in proper position.`

3. AV device for coupling a walking plow to sulky plow, comprising a barmember having averticalupper portion, an intermediate portion and a horizontal lower portion, a :strap member of greater length than :said-"member and lying againstthe lower and intermediate portions and spaced from and lying parallel with said upper portion, ,means forse'curing -said-upperbar portion and the spacedstrap portion together, each on one sidey of a: plow! beam of said-sulky plow, and a connecting member pivotally -carriedfuponthe freeend of said horizontal portion for attachment to the beam of` a walking plow.

4. In a coupling device for use inconnection with a'sulky plow-and a walking plow, afbar'member havingy avertical upper ortion an intermediate ortion and a 3 lower horizontal portion, a, strap member of greater length than said bar member and' lying against the lower and intermediate portions and spaeedffroin and lying parallel With said upper portion, means 'for securing said upper bar portion and the spaced strap portion together7 each on one side of a plow beam of said sulky plow, apair of oppo-4 sitely directed yokes pivotally secured at v* the free end of said horizontal port-ion, one 10 y thereof being adapted for connection to ya Walking plow, and means for connecting said other yoke to the orwardpart of the i Sulky plow `for bracing the device.

In testimony whereof, kI' atlix my signa- 11'y ture hereto.
